State agency greenhouse gas reporting

Washington is dedicated to reducing greenhouse gas emissions to help slow the impacts of climate change. State agencies are joining the effort. With direction from the Legislature, state agencies are working with us to monitor and reduce their emissions.


State Agency Climate Leadership Act

In 2020, the Legislature and Governor updated the State Agency Climate Leadership Act codified in RCW 70A.45. The Act directs state agencies, including universities, colleges, and community and technical colleges to lead by example in reducing their greenhouse gas (GHG) emissions to:

  • 15% below 2005 baseline by 2020
  • 45% below 2005 by 2030
  • 75% below 2005 by 2040
  • 95% below 2005 by 2050,  achieve net zero

To track state agencies’ progress toward meeting these limits, each covered agency must meet the following reporting requirements:

  1. Each year, estimate emissions using an emissions calculator provided by the Department of Ecology, and;
  2. Every even-numbered year, report on the following to the State Efficiency and Environmental Performance Office (SEEP) at the Department of Commerce:
    • Actions taken over the last biennium to meet these emission reduction targets
    • Actions planned for the next two biennia to meet emission limits;
    • Long-term strategy for meeting the emission limits.

Prior years' reports

Emissions reporting documents and instructions

Collecting emissions data is Ecology’s responsibility and working with agencies on emission reduction strategies is SEEP’s, however, the two agencies have collaborated to combine the reporting requirements to simplify the process for state agencies. All reporting requirements can be met using the calculator and strategy template below. Both reports are due May 20th.  See the instructions document for directions on completing the calculator and strategy template, and how to upload the completed reports and supplemental documents to SAGE.

For questions regarding emission reduction strategies, contact the SEEP office. For questions regarding the emissions calculator or uploading documents to SAGE, contact Stacey Waterman-Hoey.

Upcoming training

These training events are open to state agency emissions reporters. Invitations will be emailed directly to our list.

Other required greenhouse gas reports

Some agencies emit larger amounts of greenhouse gases and have additional reporting requirements to EPA and us. Visit EPA's greenhouse gas program to determine if your agency is required to report under federal requirements and visit our facilities greenhouse gas reporting page to check for additional state reporting requirements.
